Brief Summary

This study aims to compare the effects of intraoperative intravenous lidocaine and intravenous remifentanil on postoperative pain management in patients undergoing laparoscopic cholecystectomy under general anesthesia. Although laparoscopic procedures are minimally invasive, patients frequently experience postoperative pain. Multimodal analgesia techniques are recommended to optimize pain control and recovery while minimizing opioid-related adverse effects. In this prospective observational study, adult patients (ASA I-II) aged over 18 years who provided written informed consent were included. Standard intraoperative monitoring was performed. Anesthesia induction consisted of fentanyl, lidocaine, propofol, and rocuronium, with maintenance using sevoflurane. Hemodynamic parameters were recorded throughout the procedure. For postoperative analgesia, intravenous paracetamol and tramadol were administered before the end of anesthesia. The primary objective is to evaluate whether intravenous lidocaine provides postoperative analgesic efficacy and recovery quality comparable to remifentanil, and to determine its potential role as an opioid-sparing alternative in laparoscopic cholecystectomy.

Conditions

Colicystitis

Outcome Measures

Primary Outcomes (1)

• Postoperative Pain Score (NRS)

  Postoperative pain intensity will be assessed using the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst pain imaginable). Pain scores at rest will be assessed at 30 minutes and at 2, 6, 12, and 24 hours postoperatively. The comparison between the lidocaine and remifentanil groups will determine the effect of intraoperative intravenous lidocaine versus remifentanil on postoperative analgesia.

  Within 24 hours after surgery

Secondary Outcomes (7)

• time to first rescue analgesia

  From the end of surgery until the first administration of rescue analgesia, up to 24 hours postoperatively.

• Postoperative Analgesic Requirement

  First 24 hours postoperatively

• Recovery Profile

  First 24 hours postoperatively

• Postoperative nausea and vomiting

  First 24 hours postoperatively

• Time to first mobilization

  From the end of surgery until first mobilization, up to 24 hours postoperatively.
